Geotechnical Engineering

Tonkin delivers complete geotechnical solutions to a range of disciplines, with specialisation in local and state government infrastructure projects.

Tonkin scopes and leads geotechnical investigations, carefully considering the impact of the encountered ground conditions on a range of design solutions. We work with our clients and project teams on the delivery of civil and structural infrastructure projects across water, transport, waste and land development sectors. 

Our team has a strong understanding of how ground conditions can influence and inform design and construction. We pride ourselves on providing intelligent geotechnical inputs using our diverse range of technical skills. We provide practical and concise geotechnical solutions to maximise value to our clients. 

We use advanced design methods including finite element analysis, limit equilibrium slope stability and pile analysis software to provide geotechnical support to a range of complex projects.

Tonkin is the preferred geotechnical provider of reputable contractors due to our collaborative and pragmatic approach to the delivery of geotechnical services, integrating our Geotechnical Engineers into diverse project teams including clients, designers and contractors to provide inputs that inform all stakeholder requirements.
